Question

a) Write the balanced chemical equations with conditions involved
in the preparation of Nitric acid by ostwald's process.​

Answer 1

Explanation:

Nitric acid in Ostwald process manufactured by the oxidation of ammonia.

2NO(g) + O2(g) → 2NO2(g)

Nitrogen dioxide so formed, dissolves in water to give HNO3.

3NO2(g) + H2O (I) → 2HNO3(aq) + NO(g)

Dilute nitric acid on distillation followed by dehydration using conc. sulphuric acid gives 98% nitric acid.
